Charting unexplored territories: Milton Mogotsi, UFS PhD student, clinches victory in National 3MT Competition, unravelling infant enteric virome complexities, poised to revolutionise virology.

Milton Mogotsi, a PhD student at the University of the Free State (UFS), has secured a remarkable victory in the esteemed National 3 Minute Thesis competition (3MT), rising above formidable competition nationwide. This achievement follows Mogotsi’s earlier successes at faculty and institutional levels, where his presentations on the enteric virome of infants in the Free State stood out for their brilliance and significance.

The annual competition serves as a platform for postgraduate students to enhance their academic, presentation, and research communication skills by succinctly explaining their research to an intelligent but non-specialist audience within a concise 3-minute timeframe.

Reflecting on his initial reaction to the news, Mogotsi expressed a mix of shock and excitement. “I was genuinely shocked and excited when declared the winner,” he shared. This victory marked a significant milestone for Mogotsi, as a first-time participant, showcasing the excellence of both the UFS and the Faculty of Health Sciences.

Exploring uncharted territories

Mogotsi’s groundbreaking research delves into the unexplored domain of the enteric virome in infants, a subject inspired by his earlier master’s study in microbiology. “I was first introduced to this research during my master’s degree, and compelling findings motivated me to pursue further studies,” explained Mogotsi. Guided by his mentor, Prof Martin Nyaga, Mogotsi's doctoral journey unfolded into a profound exploration of the complexities of viruses colonising infants' guts and their implications on infant health.

Sharing key findings, Mogotsi highlighted that, despite detecting several disease-causing viruses in infants’ guts, none exhibited clinical symptoms. This emphasises the role of immunity and protective measures like breastfeeding. He also identified plant viruses, potentially transmitted through the environment or food sources, raising intriguing questions about infants’ exposure.

His pioneering use of viral metagenomics in unravelling the enteric virome’s complexity underscored its potential in understanding human health and disease. “Viral metagenomics has become a fundamental tool, shedding light on the composition of the infant’s enteric virome,” explained Mogotsi. 

Navigating challenges

Despite challenges, including disruptions due to COVID-19 and participant withdrawals, Mogotsi persevered, underscoring the importance of a longitudinal approach in comprehending the infant virome’s development over time. His success in the competition not only boosted his confidence but also expanded his networks, providing invaluable opportunities to present his findings internationally.

Mogotsi's advice to aspiring researchers mirrors his own journey: clarity of purpose, resilience in the face of challenges, fostering mentor relationships, and making the most of available resources. His groundbreaking work is poised to influence policy, guide vaccine strategies, and reshape our understanding of infant health.

As Mogotsi approaches the completion of his PhD, the future holds promising horizons for this trailblazing researcher, poised to leave an indelible mark on the world of virology and infant health.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
